Hi
I have a power supply 6675A which output is tripped to OT (Over Temperature) when power on . Already check the RT300 (Thermistor), R530 (10k) and U513 (comparator) components but none of them is damaged. I need help. Please someone tell me which part will make the OT tripped?
Thanks
Atiq

Were you able to resolve the OT issue? It could also have been that there was a failure somewhere else causing the OT event. Please let us know.
Yup in the service manual to check the thermistor and comparator and i did that but found that the thermister just for fan speed control not for OT trip.
No, i still not able to fix it. Hope you guys can help me.
Thank you so much.
